Amethyst False Spirea, Astilbe, False Spirea
General Description
Amethyst astilbe is a clump-forming, herbaceous perennial with summertime plume flowers. It is a relatively tall hybrid cultivar with green leaves and a tall inflorescence of lilac-pink flowers which bloom in midsummer.
Amethyst false spirea requires full sun to partial shade and must be grown in moist, well-drained soils and perform best in shady locations. The flowerheads fade to attractive shades of brown in the fall, providing landscape interest through winter. They function best in shade gardens, borders, rock gardens, and are used for waterside plantings and should be divided every 3-4 years when overcrowding occurs.
